Electrochemical reduction of CO2 (CO2RR) into value‐added products is a promising strategy to reduce energy consumption and solve environmental issues. Formic acid/formate is one of the high‐value, easy‐to‐collect, and economically viable products.

Core‐shell nanostructured materials with excellent physicochemical...
Photodynamic therapy (PDT) can generate reactive oxygen species (ROS) to cause cell apoptosis and induce immunogenic cell death (ICD) to activate immune response, becoming a promising antitumor modality. However, the overexpressions of indoleamine 2,3‐dioxygenase (IDO) and programmed cell death ligand 1 (PD‐L1) on tumor cells would reduce cytotoxic T cells infiltration and inhibit the immune activation...
Twist‐angle two‐dimensional (2D) systems are attractive in their exotic and tunable properties by the formation of the moiré superlattices, allowing easy access to manipulating intrinsic electrical and thermal properties.

Adjusting the local coordination environment of single‐atom electrocatalysts is a viable way to improve catalytic performance. The diversity of coordination geometric structures is limited to the traditional in‐plane configuration, with only a little consideration paid to out‐of‐plane configurations due to the lack of suitable carriers and fabrication methods. This study reports out‐of‐plane coordination...
Bimetallic SbSn alloy stands out among the anode materials for sodium‐ion batteries (SIBs) because of its high theoretical specific capacity (752 mAh g−1) and good electrical conductivity.
